Primary health care providers knowledge of dementia and cognitive assessment tools for elderly populations in Southeast Nigeria: A pilot survey.

Objectives: Primary health care remains the widely available first point of medical care in Nigeria and in other low- and middle-income countries. Recognizing the rising prevalence of dementia in these settings, primary healthcare providers should be trained on cognitive assessment. However, little is known about the current Nigerian primary healthcare providers' knowledge of dementia, cognitive assessment tools, and use in elderly populations. The aim of this study was to evaluate primary healthcare providers' knowledge of dementia and cognitive assessment tools in Southeast Nigeria in preparation for the introduction of digital tablet-based assessment tool. Methods: This is a cross-sectional mixed method descriptive pilot survey carried out in a comprehensive healthcare center affiliated with Nnamdi Azikiwe University Teaching Hospital. Fifty healthcare workers participated. Convenience sampling was employed involving all consenting primary healthcare providers in comprehensive healthcare center-Nnamdi Azikiwe University Teaching Hospital. A structured questionnaire was distributed for generation of both qualitative and quantitative data. Result: The mean age of the 50 primary healthcare providers was 36.6 years, with females constituting 80%. Mean practice duration was 10.8 years. Their response on the mean age at which patients may need a cognitive assessment was reported as 52.8 years. Primary healthcare providers reported that dementia is associated with memory loss and can be genetically inherited. None of the respondents were familiar with Montreal cognitive assessment, or any form of tablet-based cognitive assessment tool. Most (86%) knew about the mini mental state examination. Conclusion: Primary healthcare providers are deficient in knowledge of dementia Alzheimer's or cognitive assessment tools, and so they do not routinely carryout cognitive screening in elderly patients during clinic visits. It is important to train all cadres of primary healthcare staff on the use and benefit of cognitive assessment using culturally validated user-friendly tool to improve quality of care for the elderly population.

A Systematic Review and Meta-Analysis of the Prevalence of Triplex Infections (Combined Human Immunodeficiency Virus, Hepatitis B Virus, and Hepatitis C Virus) among Pregnant Women in Nigeria.

Objective: We systematically identified the prevalence of triplex infections (combined human immunodeficiency virus (HIV), hepatitis B virus (HBV), and hepatitis C virus (HCV)) in pregnancy. Methods: To gather information on the frequency of triplex infections, we searched the databases of PubMed, CINAHL, and Google Scholar. Without regard to language, we utilized search terms that covered HIV, HBV, HCV, and pregnancy. Pregnant women with triplex infections of HIV, HBV, and HCV were included in studies that also examined the prevalence of triplex infections. Review Manager 5.4.1 was employed to conduct the meta-analysis. Critical appraisal and bias tool risk data were provided as percentages with 95% confidence intervals (95% CIs), and I2 was used as the statistical measure of heterogeneity. The checklist was created by Hoy and colleagues. The study protocol was registered on PROSPERO, under the registration number CRD42020202583. Results: Eight studies involving 5314 women were included. We identified one ongoing study. Pooled prevalence of triplex infections was 0.03% (95% CI: 0.02-0.04%) according to meta-analysis. Subgroup analysis demonstrated a significantly high prevalence of 0.08% (95% CI: 0.06-0.10%; 3863 women) in HIV-positive population than 0.00% (95% CI:-0.00-0.00; 1451 women; P < 0.001) in general obstetric population. Moreover, there was a significant difference in the pooled prevalence between studies published between 2001 and 2010 and between 2011 and 2021 (0.14% (95% CI: 0.12 to 0.16 versus 0.03% (95% CI: 0.02 to 0.04%; P < 0.001))) and participants recruited in the period between 2001 and 2011 and between 2012 and 2021 (0.13% (95% CI: 0.05 to 0.21; p=0.002 versus 0.00% (95% CI: -0.00 to 0.00%; p=1.00))), respectively. Conclusion: The combined prevalence of prenatal triplex infections was 0.03%, with rates notably higher among the group of pregnant women who were HIV-positive and during the recruitment period that took place before 2012. This prevalence still necessitates screening for these infections as necessary.

Empathy as a crucial skill in disrupting disparities in global brain health.

Brain health refers to the state of a person's brain function across various domains, including cognitive, behavioral and motor functions. Healthy brains are associated with better individual health, increased creativity, and enhanced productivity. A person's brain health is intricately connected to personal, social and environmental factors. Racial, ethnic, and social disparities affect brain health and on the global scale these disparities within and between regions present a hurdle to brain health. To overcome global disparities, greater collaboration between practitioners and healthcare providers and the people they serve is essential. This requires cultural humility driven by empathy. Empathy is a core prosocial value, a cognitive-emotional skill that helps us understand ourselves and others. This position paper aims to provide an overview of the vital roles of empathy, cooperation, and interdisciplinary partnerships. By consciously integrating this understanding in practice, leaders can better position themselves to address the diverse challenges faced by communities, promote inclusivity in policies and practices, and further more equitable solutions to the problem of global brain health.

Dipstick urinalysis profile of an asymptomatic female group in south-east Nigeria.

Objectives: Routine dipstick urinalysis is a useful and inexpensive method for the early detection of asymptomatic diseases. Our study was carried out to detect the prevalence of urinary abnormalities among an apparently asymptomatic healthy female group and emphasize the value of routine dipstick urinalysis. Methods: A cross-sectional study was carried out among second to sixth (final)-year female medical students of Nnamdi Azikiwe University, Nnewi campus between 8 and 30 September 2019. A total of 100 subjects were enrolled. First-morning midstream urine samples were collected and promptly tested with dipstick strips. Subjects with abnormal findings were informed and treated appropriately. Results: In all, 54 (54%) of the subjects had urine abnormalities. Trace proteinuria was the commonest abnormality seen with a prevalence of 33%, followed by abnormal urine appearance (17%), leucocytes (14%), nitrites (8%) and urobilinogen (2%). Urine abnormalities were commoner in students who resided in the school hostel. Abnormal urine appearance was significantly associated with nitrites (0.003) and leucocytes (0.001). Conclusion: Routine dipstick urinalysis should be performed among students and apparently healthy individuals for early detection and diagnosis of renal diseases to facilitate quick interventions and prevent further progression.

Mother-to-child transmission of human immunodeficiency virus, hepatitis B virus and hepatitis C virus among pregnant women with single, dual or triplex infections of human immunodeficiency virus, hepatitis B virus and hepatitis C virus in Nigeria: A systematic review and meta-analysis.

Objectives: To systematically review literature and identify mother-to-child transmission rates of human immunodeficiency virus, hepatitis B virus, and hepatitis C virus among pregnant women with single, dual, or triplex infections of human immunodeficiency virus, hepatitis B virus, and hepatitis C virus in Nigeria. PRISMA guidelines were employed. Searches were on 19 February 2021 in PubMed, Google Scholar and CINAHL on studies published from 1 February 2001 to 31 January 2021 using keywords: "MTCT," "dual infection," "triplex infection," "HIV," "HBV," and "HCV." Studies that reported mother-to-child transmission rate of at least any of human immunodeficiency virus, hepatitis B virus and hepatitis C virus among pregnant women and their infant pairs with single, dual, or triplex infections of human immunodeficiency virus, hepatitis B virus, and hepatitis C virus in Nigeria irrespective of publication status or language were eligible. Data were extracted independently by two authors with disagreements resolved by a third author. Meta-analysis was performed using the random effects model of DerSimonian and Laird, to produce summary mother-to-child transmission rates in terms of percentage with 95% confidence interval. Protocol was prospectively registered in PROSPERO: CRD42020202070. The search identified 849 reports. After screening titles and abstracts, 25 full-text articles were assessed for eligibility and 18 were included for meta-analysis. We identified one ongoing study. Pooled mother-to-child transmission rates were 2.74% (95% confidence interval: 2.48%-2.99%; 5863 participants; 15 studies) and 55.49% (95% confidence interval: 35.93%-75.04%; 433 participants; three studies), among mother-infant pairs with mono-infection of human immunodeficiency virus and hepatitis B virus, respectively, according to meta-analysis. Overall, the studies showed a moderate risk of bias. The pooled rate of mother-to-child transmission of human immunodeficiency virus was 2.74% and hepatitis B virus was 55.49% among mother-infant pairs with mono-infection of HIV and hepatitis B virus, respectively. No data exists on rates of mother-to-child transmission of hepatitis C virus on mono-infection or mother-to-child transmission of human immunodeficiency virus, hepatitis B virus, and hepatitis C virus among mother-infant pairs with dual or triplex infection of HIV, hepatitis B virus and HCV in Nigeria.

Pregnant women's hepatitis B vaccination coverage in Nigeria: a national pilot cross-sectional study.

OBJECTIVE: To determine the hepatitis B vaccination coverage, full-dose (⩾3) coverage and the associated factors affecting uptake among pregnant women. METHODS: This was a cross-sectional study among pregnant women attending antenatal care in six tertiary hospitals across all the geopolitical zones of Nigeria. Pregnant women who consented to the study completed screening questions about their hepatitis B vaccination status and coverage. The main outcome measures were hepatitis B vaccination coverage rate, dose, and factors affecting uptake. Bivariate analysis was performed by the chi-square test and conditional logistic regression analysis was used to determine variables associated with uptake of the vaccination. Odds ratios (ORs) and adjusted odds ratios (aORs) were calculated and statistical significance was accepted when p-value was < 0.05. RESULTS: Of 159 pregnant women who completed the interview questions, 21 [13.2%, 95% confidence interval (CI) 7.9-18.5%] were vaccinated for hepatitis B for one to three doses. The numbers of doses received were: three doses (8/159, 5.0%), two doses (5/159, 3.1%), and one dose (8/159, 5.0%). The reasons for non-uptake of vaccination included: lack of awareness of the vaccine 83/138 (60.1%), inadequate access to vaccine 11/138 (8.0%), and positivity to hepatitis B virus 10/138 (7.2%). The uptake of hepatitis B vaccination was significantly affected by the level of education (OR 0.284, 95% CI 0.08-1.01, p = 0.041), but in multivariable logistic regression, adjusted for confounders, the association between hepatitis B vaccination and participants' level of education (aOR 3.09; 95% CI 0.95-10.16; p = 0.061) did not remain significant. CONCLUSIONS: In Nigeria, the national hepatitis B vaccination coverage among pregnant women appears poor, with the full-dose coverage even poorer. The level of education was not positively associated with uptake of hepatitis B vaccination, while lack of awareness of the vaccine was the commonest reason for non-uptake.

Awareness and prevalence of hepatitis C virus infection among pregnant women in Nigeria: A national pilot cross-sectional study.

BACKGROUND: There are no national data on hepatitis C virus awareness and burden among pregnant women to justify its routine screening. OBJECTIVES: To investigate awareness, seroprevalence and risk factors for hepatitis C virus infection among pregnant women in Nigeria. METHODS: A total of 159 pregnant women from antenatal clinics across six geopolitical zones in Nigeria consented to anti-hepatitis C virus testing which was confirmed using polymerase chain reaction technique. Confirmed hepatitis C virus positive women were further tested for hepatitis B and HIV. Participants were evaluated for risk factors for hepatitis C virus. Odds ratios, adjusted odds ratios, and their 95% confidence intervals (CIs) were determined, and p-values of <0.05 were considered significant. RESULTS: Of 159 participants, 77 (48.4%; 95% confidence interval = 38.2%-60.5%) were aware of hepatitis C virus infection and awareness of hepatitis C virus was associated with young age (odds ratio = 2.21; 95% confidence interval = 1.16-4.21), high educational level (odds ratio = 3.29; 95% confidence interval = 1.63-6.64), and participants' occupation (odds ratio = 0.51; 95% confidence interval = 0.26-0.99). In multivariable logistic regression, adjusted for confounders, the association between awareness of hepatitis C virus and participants' young age (adjusted odds ratio = 1.60; 95% confidence interval = 1.09-2.35; p = 0.018) and high educational level (adjusted odds ratio = 1.48; 95% confidence interval = 1.17-1.86; p = 0.001) remained significant. Hepatitis C virus seroprevalence was found to be 1.3% (95% confidence interval = 0.2%-4.5%). All (100.0%, 95% confidence interval = 12.1%-100.0%) the hepatitis C virus-positive participants and 99 (63.1%, 95% confidence interval = 51.3%-76.8%) hepatitis C virus-negative participants had identifiable hepatitis C virus risk factors. Dual seropositivity of anti-hepatitis C virus/anti-HIV and anti-hepatitis C virus/hepatitis B surface antigen each accounted for 0.6%. The most identified risk factors were multiple sexual partners (15.7%), shared needles (13.8%), and blood transfusion (11.3%). There was no significant association between the risk factors and hepatitis C virus positive status. CONCLUSION: Awareness of hepatitis C virus infection among pregnant women in Nigeria is low and those aware are positively influenced by young age and high educational level. The prevalence of hepatitis C virus infection is high and provides preliminary evidence to justify antenatal routine screening.

Prevalence, seroconversion and mother-to-child transmission of dual and triplex infections of HIV, hepatitis B and C viruses among pregnant women in Nigeria: study protocol.

BACKGROUND: Nigeria contributes significantly to the global burden of HIV, Hepatitis B and C infections, either singly or in combinations, despite progress in HIV care regionally and globally. Although some limited data on mono infection of HIV, Hepatitis B and C virus infections do exists, that of dual and triplex infections, including seroconversion and mother-to-child transmission (MTCT) rates necessary for planning to address the scourge of infections in pregnancy are not available. OBJECTIVES: To determine the seroprevalence, rate of new infections, MTCT of dual and triple infections of HIV, Hepatitis B and C viruses and associated factors, among pregnant women in Nigeria. METHOD: A multicenter prospective cohort study will be conducted in six tertiary health facilities randomly selected from the six geopolitical zones of Nigeria. All eligible pregnant women are to be tested at enrollment after informed consent for HIV, Hepatitis B and C virus infections. While those positive for at least two of the infections in any combination will be enrolled into the study and followed up to 6 weeks post-delivery, those negative for the three infections or positive for only one of the infections at enrolment will be retested at delivery using a rapid diagnostic test. On enrolment into the study relevant information, will be obtained, and laboratory test of CD4 count, liver function test and full blood counts, and prenatal ultrasonography will also be obtained/performed. Management of mother-newborns pairs will be according to appropriate national guidelines. All exposed newborns will be tested for HIV, HBV or HCV infection at birth and 6 weeks using PCR technique. The study data will be documented on the study case record forms. Data will be managed with SPSS for windows version 23. Ethical approval was obtained from National Health Research Ethics Committee (NHREC) (NHREC/01/01/2007-23/01/2020). CONCLUSION: Pregnant women with multiple of HIV, HBV and HCV infections are at increased risk of hepatotoxicity, maternal and perinatal morbidity and mortality. Additionally, infected pregnant women transmit the virus to their unborn baby even when asymptomatic. Children born with any of the infection have significantly poorer quality of life and lower five-year survival rate. Unfortunately, the seroconversion and MTCT rates of dual or triplex infections among pregnant women in Nigeria have not been studied making planning for prevention and subsequent elimination of the viruses difficult. The study is expected to fill this knowledge gaps. Nigeria joining the rest of the world to eliminate the triple infection among children rest on the availability of adequate and reliable data generated from appropriately designed, and powered study using representative population sample. The establishment of the three-in-one study of prevalence, rate of new infection, rate and risk factor for MTCT of dual and triple infection of HIV, Hepatitis B and C viruses among pregnant women in Nigeria is urgently needed for policy development and planning for the improvement of the quality of life of mothers and the elimination of childhood triplex infection.

Antibiotic susceptibility pattern of genital tract bacteria in pregnant women with preterm premature rupture of membranes in a resource-limited setting.

OBJECTIVE: To identify microbes prevalent in the genital tract of pregnant women with preterm premature rupture of membranes (PPROM) and to assess the susceptibility of the microbial isolates to a range of antibiotics to determine appropriate antibiotics for treating cases of PPROM in resource-limited settings. METHODS: A prospective cross-sectional study was undertaken involving women with (n=105) and without (n=105) a confirmed diagnosis of PPROM admitted to Nnamdi Azikiwe University Teaching Hospital, southeast Nigeria, between January 1, 2011, and April 30, 2013. Endocervical swabs were collected from all participants and examined microbiologically. Antibiotic sensitivity testing was performed using Kirby-Bauer disk diffusion. RESULTS: Streptococcus spp., Staphylococcus aureus, and Escherichia coli were significantly more prevalent among women with PPROM than among those without PPROM (P<0.01). Among the antibiotics considered safe to use during pregnancy, the bacteria were most sensitive to ampicillin-sulbactam, cefixime, cefuroxime, and erythromycin. CONCLUSION: For the first 48hours, women with PPROM should receive an intravenous dose combining ampicillin-sulbactam, cefixime, cefuroxime, or erythromycin with metronidazole followed by oral administration of the chosen antibiotic combination to complete a 7-day course.

Prevalence, correlates and pattern of hepatitis B surface antigen in a low resource setting.

BACKGROUND: Hepatitis B virus (HBV) infection in Nigeria has remained a Public Health issue. It is a major cause of mortality, especially in developing countries. Vertical transmission of hepatitis B virus infection is thought to be a major route of transmission in low resource areas. In spite of this, routine antenatal screening for hepatitis B infection is not yet practiced in many Nigerian hospitals. This paper present the findings of a study conducted among antenatal women in Nnewi, Nigeria. METHODS: It was a cross-sectional study carried out over a 3-month period (August-October, 2009). Recruitment of 480 women attending antenatal clinics in Nnewi, Nigeria was done by simple random sampling using computer generated random numbers. HBsAg screening was done using rapid ELISA Kits. Statistical analysis was computed using STATA 11 package. The results were subjected to analysis using cross tabulations to explore statistical relationships between variables. Chi square test was used to explore proportional relationship between groups. The level of statistical significance was set at p < 0.05 (providing 95% confidence interval). RESULTS: Four hundred and eighty pregnant women were recruited into the study. Of these, 40 tested positive to HBsAg, accounting for 8.3% of the sample population. The age of the subjects studied varied from 14 to 45 years (mean age--24.3 years) while the mean parity was 2.18. The HIV/HBV co-infection rate was 4.2%. The vertical transmission rate was 51.6%. There were statistically significant relationships between HBV infection and previous history of tribal marks/tattoos (χ2 = 27.39, P = 0.001, df = 1), history of contact with previously infected HBV patients (χ2 = 23.11, P = 0.001, df = 1) and occupation of the women (χ2 = 51.22, P = 0.001, df = 1). Multiple sexual partners, blood transfusion, dental manipulations, sharing of sharps/needles, and circumcision were not significant modes of transmission. There was no statistically significant relationship between maternal age, educational level and HBV infection. CONCLUSION: The authors argued that hepatitis B screening in pregnancy should be made routine practice in Nigeria because of the low pick up rate of the infection based only on risk factors for the disease.
